Abstract
A paper decoration is made by immersing a perforated mold having a predetermined shape into a liquid pool containing paper-making ingredients. A layer of the ingredients deposited on the mold is then dried in situ, after which, the dried paper layer is detached and formed into the paper decoration.
Claims
exact text as granted — not AI-modifiedWhat is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims.
1. A method of making a paper decoration, comprising the successively performed steps of: (a) shaping a perforated mold with a predetermined shape; (b) positioning a sheet of graphic material on the mold; (c) immersing the perforated mold and the sheet into a liquid pool containing paper fibers; (d) removing the mold and the sheet from the pool to deposit the paper fibers on the mold and the sheet; (e) drying the deposited fibers in situ on the mold to form a dried paper layer having said predetermined shape with the sheet integrated therein; (f) detaching the dried paper layer and the integrated sheet from the mold; and (g) forming the dried paper layer and the integrated sheet into the paper decoration.
2. The method according to claim 1, wherein the shaping step is performed by providing a wire mesh, and configuring the wire mesh with a three-dimensional shape.
3. The method according to claim 1, wherein the paper fibers are wood pulp.
4. The method according to claim 3, wherein the paper fibers are re-cycled paper fibers.
5. The method according to claim 3, wherein the pool also contains binders and glue.
6. The method according to claim 3, wherein the pool also contains coloring dyes.
7. The method according to claim 1, wherein the immersing and removing steps are performed for a plurality of times before performing the drying step.
8. The method according to claim 1, wherein the drying step is performed by allowing the deposited ingredients to air-dry in situ on the mold.
9. The method according to claim 1, wherein the drying step is performed by heating the deposited materials in situ on the mold.
10. The method according to claim 1, wherein the drying step is performed by heating the mold.
11. The method according to claim 1, wherein the forming step is performed by cutting the dried paper layer into a rosette flower shape having petals emanating radially from a center of the dried paper layer, and wherein the mounting step includes mounting a plurality of the rosette flower shapes on a stem.Cited by (0)
